Don Quixote has become so entranced by reading chivalric romances that he determines to become a knight-errant himself. In the company of his faithful squire, Sancho Panza, his exploits blossom in all sorts of wonderful ways. While Quixote's fancy often leads him astray--he tilts at windmills, imagining them to be giants--Sancho acquires cunning and a certain sagacity. Sane madman and wise fool, they roam the world together, and together they have haunted readers' imaginations for nearly four hundred years.
